Without cause to believe that exchange did not happen, we presume it did, and then why not presume Francis was talking past Biden to some U.S. Catholic bishops?
To say Francis does not suffer fools well and yet cordially met Joe Biden is to overlook that Francis has to suffer the worse of his U.S. Catholic bishops.
We are fortunate that Francis is an apolitical Pope, yes/no?
UPDATE: Breitbart. However bad some might want to paint Facebook, some exist to accord Facebook lesser evil status in one-on-one comparisons.
